30 Using the following equation determine the average concentration (moles per liter) of acetic acid (CH,CO,H) present in your vinegar. Record the concentration in Data Table 2 average volume of NaOH (mL) X 1L NAOH 1000 mL NAOH 0,5 mol NaOH 1. NaOH 1 mol CH4COH 1 mol NaOH = average moles of CH,CO,H average moles of CH,CO,H 5.0 ml, vinegar 1000 ml IL = Concentration of CH.CO, H (M=mol/L) 31 Using the following equation and your result from Step...
a-c 5, Vinegar should contain more than 4% acetic acid (CHCOOH, molar mass 60.0 g mor) 25.0 mL of vinegar are diluted to 100.0 mL and 10.0 mL samples of this solution are titrated against 0.100 mol L-NaOH solution. An average of 18.1 mL NaOH are required to neutralize the vinegar. You will need to calculate the concentration of the diluted solution and hence the percentage concentration of acetic acid in the original vinegar via the following questions: CH COOH(aq)...

5. Acetic acid (HC,H,Os) is an important component of vinegar. A 10.00-ml sample of vinegar is titrated with 0.5052 M NaOH, and 16.88 mL are required to neutralize the acetic acid that is present a. Write a balanced equation for this neutralization reaction. b. What is the molarity of the acetic acid in this vinegar? c. If the density of the vinegar is 1.006 g/mL, what is the mass percent of acetic acid in the vinegar? 6. How many milliliters...
